The Lash & Brow Growth Serum by ZOE AYLA - VOID, as reviewed by Olive, has some mixed feedback. Olive mentions that the serum tends to go everywhere when opening the tube, making it messy to use. Storing it upside down helps with dispensing the serum, but it results in serum accumulating in the lid, requiring caution when opening. Additionally, Olive finds the applicator to be awkward and suggests trying a mascara-like brush for comparison. Despite these drawbacks, the serum has been used consistently for two weeks. Overall, the Lash & Brow Growth Serum by ZOE AYLA - VOID may have potential benefits for lash and brow growth, but improvements in packaging and applicator design could enhance the user experience.
